COTTON-GIN CONDENSER.

To all whom itmayrconccm: l y Be it known that I, MATTHEW J. GROCKER,

a citizen of England, and a resident of Helena, in the county of Phillips and State of Arkansas, have made certain new and useful Improvements in Cotton-Grin Condensers, of which the following is a specification. y r j My invention relates to cotton condensers,- and has. reference more particularly to condensers used in connection with cotton gins.

An object of the invention is; to-provide the gin.

. Another object is to provide a condenser that will also prevent the passage .of dust anddirt along with the condensed cotton. Another object is to provide means for from cotton after leaving the gin. V

\Vith these and other objects in view my invention consists in certain novel features of construction, arrangement and combination of parts,' as will be hereinafter fully described and pointed out in the claims, reference beingv had to the accompanying drawings, in which:

. Figure 1 is a transverse vertical section through the device; y

Fig. 2 is a longitudinal vertical section of same;

Fig. 3 is an enlarged side elevation of a i gear wheel driving the condensing cylinder;

Fig. 4c is a, plan view of the baflie or defiector support.

In the drawings which show a practical embodiment of my improvement Ilpropose to use a supporting frame composed of uprights 10 connected by upper cross beams 11 and lower cross beams 12. Mounted on the top of the frame on the cross bars 12 is a rigid shaft having alined end portions Specification of Letters Patent. P t t N v, 4, 1919, Application filed June 23, 1919.

and inwardly forming a chute or fine 21 through which the dust and other debris that flows through the wire screen may pass.

Through one side (the side nearest the gin) an opening of suitable extent is made and. in this is inserted the flue spout 22 leadingfrom the gin, said flue being 801116. What upwardly inclinedand extending very close to the periphery of the screen 17 at its upper portion. lathe-opposite wall of theficasing, but adjacent the lower .part of the periphery of the cylinder are disposed the dofling rolls 23, and above said rolls in the wall is introduced a slab 24:.

Within the tubular screenlf. is mounted a stationary baffleor deflector which comprises a sheet metal plate, designated generally at 24, said plate being of suchlength as to nearlyfill the interior of the cylinder 17 longitudinally, leaving just sufficient spaceto permit the cylinder headsto rotate, as the baflie remains stationary. The width of baffle or deflector 24 is such as to nearly fill the cylinder transversely, leaving suflicient space to permit the revolutionof the cylinder around such baffle The baflie or deflector is of a peculiar shape being struck ona compound or ogee shape, the upper concave portion 25 facing and extending toward the inlet flue from the gin, whilethe lower portion 26 faces toward the doiiing rolls 23, the curvatures of25 and 26 being such that if continued that of I25 would approximate the end of flue and that of 26 would aproximate the lower periphery of the lower doifing roll 23.. By thi construction and arrangement of the baffle, little or not air reaches the circumference of thescreen cylinder 17 be-. :tween'the points 00 and y, so that the con- 28 rigidly secured to the ogee curve bafiie, said ribs conforming in shape to the shape of the baffle or deflector and the braces 28 holding the same at the proper angle to fine from. the gin.

A sprocket gear 29 having a hub 30 is mounted on hub 15 of the cylinder and is rigidly connected therewith by being bolted or otherwise.

While it has been stated that the baflle board or deflector may be made of sheet metal, it is of course obvious that any other suitable material may be used for this purpose, and the deflector may be placed at any angle to best deflect the current of air which carries dust and debris, downward through the flue, a current being created in that direction either by suction or otherwise.

It will be noted that by offsetting the shaft carrying the deflector a greater unobstructed Space is provided for the efiect of the down draft of air on the dust and dirt, and hence practically all of the dust and dirt will be pulled outas it were from the cotton after leaving the gin.

The operation of the device is as follows:

The cotton passes through the gin (not shown) at the left of flue and the saws at the gin pull the lint from the seed and the brush of the gin takes the lint from the saws and creates a draft which drives the cotton through the flue and against the rotary wire screen 17. This screen catches and holds the cotton lint, but the dust, dirt and other debris passes through the screen and strikes againstthe deflector 24:, and drops down through the discharge or flue" 21, the offsetting of the deflector and its angular arrangement relative to the intakeof air adding greatly to the effectiveness of'the device in accomplishing its stated purposes. I

It should be noted that the concave por tion 25 of the deflector presented to the flue 22 is of greater extent than convex portion at this side, hence a flared out or fan shaped area will be. produced through which the draft will act on the dust or dirt.

I claim: j

1., The device as herein characterized and comprising a casing, having a combined air and lint inlet, an air outlet and lint outlet, a tubular reticulated screen mounted for rotation within said casing and interposed between said inlets and outlets, and a stationary baffle comprising a plate obliquely disposed within said tubular screen."

2. A device as herein characterized and comprising a casing having a combined air and lint inlet, an air and dust outlet, and a lint outlet, a tubular screen mounted for rotation within the casing and between said inlets and outlets, and a stationary baffle plate within said screen, said bafl'le comprising a plate disposed'obliquely' across nearly the-breadth of the screen and within the same, and away from said air and lint inlet.

3. A device as herein characterized consisting of a casing having combined air and lint inlets, and air and cotton lint outlets, a tubular screen mounted for rotation within said casing, and a stationary baflle plate or deflector mounted within'said'screen, said deflector having reversely curved portions opposing the combinedair and cotton inlet of the casing. V

at A device as herein characterized and comprising a casing having a' combined air and cotton inlet and air and cotton outlets, a tubular condensing screen mounted to rotate in said casing and in the path of said air and cotton inlet, and a deflector plate stationarily mounted within said screen, said deflector consisting of an ogee curve and ofl'set from the axis of the screen.

5. A cotton gin condenser comprising a combination, a supporting frame, a cranked shaft rigidly mounted on said frame, a tu-- bular reticulated condensin cylinder rotatably mounted on said rigidly mounted cranked shaft, a casing within which said cylinder rotates, said casing havinglateral inlets and outlets disposed in opposite sides anda draft flue at its lower end, an ogee curved deflector plate within said condens ing cylinder and rigidly secured to thecranked portion of the aforesaid shaft, and means for rotating said condensing cylinder. r
